UPDATE is for changing values in existing rows. It appears you want to
add new information. Use INSERT.
$query= "INSERT tablename SET (username, email, location) VALUES(
$username, $email, $location)";
Note that a WHERE condition is incorrect for INSERT.
Your UPDATE syntax is not correct either. Note that you need only one
query to update any or all of the columns in a row.
Using your example:
$query="UPDATE tablename SET username=$username, email=$email,
location=$location WHERE userID=$id";
Finally, your "Flash of Success" is not useful because it will print
even when the query fails.
